V1647 ORIONIS = IRAS 05436-0007
     N. N. Samus, Institute of Astronomy, Moscow, informs us that
the designation V1647 Ori has been given to the variable star
associated with IRAS 05436-0007 (cf. IAUC 8284, 8289, 8290, 8303,
8306).
     S. Vig, S. K. Ghosh, and D. K. Ojha, Tata Institute of
Fundamental Research, Mumbai, in collaboration with V. K. Kulkarni
(National Centre of Radio Astrophysics, Pune), report that a radio-
continuum observation of IRAS 05436-0007, obtained at 1272 MHz
using the Giant Metrewave Radio Telescope on Feb. 14.5 UT, shows no
radio emission within a 1'.5 x 1'.5 region around IRAS 05436-0007
(R.A. = 5h46m13s.1, Decl. = -0o06'05", equinox 2000.0; from 2MASS),
with a 5-sigma upper limit of 0.15 mJy/beam (synthesized beam size
5".61 x 2".72, p.a. -48.91 deg).  All of the sources from the
NRAO/VLA Sky Survey Catalog within this region (covering a 25'-
diameter circular area centered on the nebula) were detected.


(4492) DEBUSSY
     Further to IAUC 8265 and 8292, R. Behrend writes (on behalf of
fourteen others) that photometric observations of (4492) obtained
during 2002 Oct. 30-Dec. 4 and 2004 Mar. 18-May 18 show a regularly
shaped lightcurve with period 1.108 day and amplitude 0.5 mag, with
sharp attenuations characteristic of mutual eclipse/occultation
events observed at minima of the regular lightcurve having depth
about 0.6 mag and duration about 2.5 hr -- suggesting that this is
probably a binary system, with properties similar to those of
(1089) and (1313).


COMETS C/2003 V6 AND C/2003 V7 (SOHO)
     Further to IAUC 8351, K. Battams reports measurements for
additional Kreutz sungrazing comets found on SOHO website C2 images
by T. Hoffman (C/2003 V6) and R. Matson (C/2003 V7).  The
reductions by R. Kisala and orbital elements by B. G. Marsden
appear on MPEC 2004-K34.

    Comet         2003 UT          R.A. (2000) Decl.
    C/2003 V6     Nov.  9.564      14 53.4   -18 10
    C/2003 V7          11.896      15 03.5   -18 57
